HAMMER.

SPECIFICATION formingpart of Letters Patent No. 674,640, dated May 21, 1901. Application filed October 20, 1900. as No. 33,769. (No model.)-

T0 at whom, it may concern.-

Be it known that I, FRANCIS O. W. STELTER, a citizen of the United States, residing at New York, Astoria, Long Island, in the State of New York, have invented certain new and useful Improvements in Hammers, of which the following is a specification.

My invention relates to hammers or similar tools, and more especially to what is generally known as coopers hammers, and has for its object to provide a hammer which is well adapted for tightening or driving hoops on barrels, tubs, and the like, as well as for use as an ordinary ham mer; and it consists in a hammer embodying the features of construction substantially as hereinafter more particularly set forth.

Referring to the accompanying drawings, wherein I have illustrated a preferred embodiment of my invention, Figure 1 is a perspective view of a hammer-head. Fig. 2 is an end view of the same. Fig. 3 is a perspective view of a modified form of hammerhead, and Fig. 4: is an end View of the same.

In the use of tools of this character it is desirable to have a hammer with an ordinary head or face, adapted for pounding or driv-- ing nails or the like or to be pounded upon, and also to have the hammer so constructed that it is well adapted for driving or tightening hoops on tubs, barrels, and the like, and it is to provide a tool well adapted for all these uses and which shall be simple, cheap, and effective that my invention is made.

In the drawings, A represents a hammer the body portion B of which is provided with an opening C, as shown, for the reception of the handle. The end or head D may be of any usual and desired shape, it being shown in the present instance as rectangular. The end or head E is shown as having tapered sides a a, making an elongated face having one or more grooves e e in its face. These grooves are adapted to engage the edge of a hoop when the hammer is used for applying or tightening hoops upon barrels, kegs, and the like. The tapered faces a a are curved to correspond, substantially, with the curved groove or grooves e e, and when there is more than one curved groove the curves are of different radius, adapted to fit different-sized hoops or barrels or casks to which the hoops are applied. Thus in Figs. 1 and 2 the groove 6 has a larger radius than the groove e, and it will be understood that the curvature of the groove or grooves may vary from those shown, according to the purposes for which the hammer is made.

In Figs. 3 and 4: I have illustrated a modification or extension of my invention in which the body B has two openings 0 C at right angles to each other, in either of which the handle can be inserted, and the head D, as before, may be of any desired construction. In this form the head E is provided with four grooves e e e e adjacent to its edges, and each of these grooves preferably has a different radius, so that the hammer may be used for tubs, barrels, casks, and the like and the grooves will be better adapted for the particular purpose to which the hammer is applied.

Of course it is within my invention to have different-shaped heads and to have one or a plurality of grooves of the same or different radius; but the forms illustrated are the preferable forms and serve to explain the principles of my invention, so as to enable those skilled in the art to adapt it for use for any particular purpose.

What I claim is 1. A coopers hammer, the face of which is provided with a curved groove, substantially as described.

2. A coopers hammer, the face of which is provided with a plurality of grooves, substantially as described.

5. A coopers hammer, the face of which is FRANCIS C. W. STELTER.
